timing belt was last done when the head gaskets were replaced, so i'm coming up on that service window.
after another two days driving ~50 miles each day, i can tell the engine is running better but there is still a slight intermittent miss. i can't hear it, but i can feel the vibration. also, when holding the engine at 3k rpm, i can see the engine hiccup about once every second or two.
further diagnosis will have to wait a bit since this week is busy for me. in the meantime, i'm going to empty the last 1/3 bottle of Seafoam into the intake and dump some injector cleaner in the tank
